Answer:

226.2 feet

Step-by-step explanation:

The fence around the dog's house is a circle, with a radius of 12 meters.

To calculate the distance the dog runs, we need to find the circumference of that circle, which is given by the formula:

C = 2 π r, since we know r, the calculation is easy:

C = 2  π 12 = 24 π = 75.4 feet.

The dog makes three laps around the circle before calming down... so he runs 3 times 75.4 feet.

Dogs run = 3 x 75.4 ft = 226.2 feet

Llana [10]

Answer:

  • -4

Step-by-step explanation:

<u>Given points </u>

  • (-2, 5) (1, -7)

<u>Use slope formula to find the slope</u>

  • m = (y2 - y1)/(x2 - x1)
  • m = (-7 -5)/(1 + 2) = -12/3 = -4

Slope is -4

What is the solution to the system of equations y= -5x + 30 x = 10
Arturiano [62]

Answer:

We have been given the equation:

y=-5x+30

And x=10

Substitute the given x in the given equation we get:

y=-5(10)+30

y=-50+30

On simplification we get:

y=-20

Required solution is:  x= 10 and y=-20

The solution to the system of equation is those points that satisfy the given system of equations.

20. The surface areas of two similar solids are 216 m² and 1014 m². The volume of the larger one is 2197 m³. What is the volume
Andrei [34K]

Answer:

  216 m³

Step-by-step explanation:

The ratio of linear dimensions is the square root of the ratio of area dimensions.

  s = √(216/1014) = √(36/169) = 6/13

Then the ratio of volume dimensions is the cube of that. The smaller volume is ...

  v = (6/13)³·2197 m³ = 216/2197·2197 m³ = 216 m³

The volume of the smaller solid is 216 m³.
